I play the French exclusively… After many a year playing a variety of e5 & Sicilian, I decided to employ the French to improve my game and to incorporate the Dutch defense by playing 1) d4 e6 2. C4 f5 without having to consider the Stanton gambit …
It is a counter puncher’s defense for sure… I have seen over the years that more players avoid to play against the complications arising playing the complications of the French Defense and opt to play the Exchange French (a drawish line) rather than learn to fight against it…
The French Defense is fun and helped me understand chess… After I employed it, I got over the over the 1700 hump in USCF ratings and helped me maintain a rating 2000 (plus or minus 20 points) during my active tourney life…
I like the quote but have been playing the french myself for decades .
It seems to me the French was perhaps a bit too tactical in nature, as well as too "neanderthal" in Steinitz's estimation. It was more of the chessic equivalent of two people trading punches, instead of anything methodical and "chess like"...
